Step 1: Prepare for the Task Ahead

Before diving into the deck belt replacement process, take a moment to ensure the mower is turned off and disconnect the spark plug wire to prevent any accidental starts. Park the mower on a level surface, ensuring stability throughout the procedure. Gather all the necessary tools and materials mentioned above, positioning them conveniently for easy access.

Step 2: Access the Deck Belt

To access the deck belt, you'll need to tilt the mower deck. Begin by lowering the deck to its lowest cutting height. Locate and remove the retainer springs or bolts securing the deck to the mower frame, utilizing the appropriate socket or wrench. Carefully slide out the mower deck from underneath the mower.

Step 3: Remove the Old Deck Belt

Familiarize yourself with the deck belt routing diagram, typically found on a decal attached to the mower deck or within the owner's manual. Before removing the old belt, take note of its path. Start by detaching the belt from the pulleys, paying attention to how it is threaded around each pulley. Loosen the tension on the belt by releasing the tensioner pulley or lever. Once the belt is sufficiently loose, slide it off the pulleys.

Step 4: Install the New Deck Belt

Compare the new deck belt with the old one to ensure they share the same dimensions and meet your Toro mower's specifications. Thread the new belt around the pulleys, carefully following the routing diagram you noted earlier. Verify that the belt is correctly seated in the grooves of each pulley and make any necessary adjustments to ensure proper alignment.

Step 5: Reattach the Mower Deck

Slide the mower deck back under the mower, aligning it with the mounting brackets or bolts. Reinstall the retainer springs or bolts to securely fasten the deck to the mower frame. Using the appropriate tools, tighten them to ensure the deck is stable and firmly attached.

Step 6: Test the Deck Belt

Before finalizing the process, it is crucial to check the tension of the new deck belt. Engage the mower blades and inspect the belt's alignment and tension. The belt should be taut and move smoothly around the pulleys without slipping or wobbling. If necessary, adjust the tension by tightening or loosening the tensioner pulley.
